A dangerous severe weather threat is developing for Kansas today, where a small but potent storm system in the western part of the state will intensify and move east. By late this afternoon, the storm will spawn supercell thunderstorms capable of bringing large hail and strong tornadoes to eastern Kansas and extreme western Missouri. NOAA's Storm Prediction Center has placed this region in its "Moderate Risk" area for severe weather, the second highest level of alert. Cities in the Moderate Risk area include Topeka, Kansas, and Kansas City, Missouri.
